Meanwhile, the RBI has asked banks to follow the instructions of government organisation CERT-In on ransomware, which has impacted various IT networks in over 150 countries.

One of the biggest-ever ransomware attacks continues to take computers hostage.

The phenomenon of companies failing to update their systems has been a persistent security problem for years.

Businesses and large organizations are mostly at risk of this attack because of a flaw in a Windows protocol that many businesses use to share files.

In the wake of the attack, Microsoft released a patch for computers running older operating systems, including Windows IX, Windows 8 and Windows Server 2003.

In Asia, where Friday's attack occurred after business hours, thousands of new cases were reported on Monday.

Microsoft released a patch to fix vulnerabilities in March.

It says the latest virus exploits a flaw in Microsoft Windows identified by, and stolen from, U.S. intelligence. The security flaw that hackers used to launch the attacks Friday was made public after information was stolen from the U.S. National Security Agency, which routinely searches for flaws in software and builds tools to exploit them. The WannaCry hack threatens to delete users' encrypted files in a week if a ransom of $300 isn't met - doubled if the payment isn't made in within three days.
